Whatever I do, the drawing units return to MMGS.

My approach: 

• Open my plan template
• Change the units to "Custom" and change the grams to Kg
• Save the plan as a template
• Re-save the background model (you never know)
• Close SW, Reopen

=> Plan still in MMGS

I had this issue on SW2023 SP1 and moved to SW2024 SP2 without change.

Thank you in advance,
